The World of Warcraft Bestiary (or, incorrectly, "Beastiary") initially was the first teaser web site for World of Warcraft on the Blizzard web site. It eventually turned into the Town Hall and the "bestiary" pages were only linked from pages therein.

Each of the pages of the bestiary showed an animated sequence of monster with sound and a short bit of lore. Most of the mobs were from Alliance zones, since those were implemented earlier than much of the Horde zones.
